Stirge

A stirge’s coloration ranges from rust-red to reddish-brown, with a dirty yellow underside. The proboscis is pink at the tip, fading to gray at its base. A stirge’s body is about 1 foot long, with a wingspan of about 2 feet. It weighs about 1 pound.

If a stirge hits a creature, it attaches and drains blood equal to 1d4 damage per round (on its Initiative). The creature can only be removed by killing it; any attack on the creature receives an attack bonus of +2, but any attack that misses hits the victim instead.
